The use of an endostapler in the treatment of supralevator abscess of intersphincteric origin.

2014

Aim This technical note describes the use of an endostapler for the definitive treatment of supralevator abscess upward from an intersphincteric origin. Method A two-stage treatment was performed. First an endoanal drainage was performed by inserting a mushroom catheter in the supralevator abscess cavity. In the second stage transanal unroofing of the fistula was performed with an endostapler. Results Since 2011, three patients have been treated in this way. After 2 years of follow up, none of the patients had recurrence of the abscess or been referred for anal incontinence. Conclusion The use of an endostapler in the treatment of supralevator abscess of intersphincteric origin may be an al…

Simulation of Supralevator Abscesses and Complex Fistulas in Cadavers: Pelvic Dissemination and Drainage Routes

2018

BACKGROUND: Most perianal abscesses have a cryptoglandular origin, following the pathogenesis described by Parks in 1961. Supralevator abscesses have the most uncommon location. Nevertheless, such pathology results in a high morbidity because of their difficult diagnosis and treatment. OBJECTIVE: This study aimed to deepen the knowledge of the pathogenesis and management of supralevator abscesses, as well as the complications derived from incorrect treatment, by using simulation in cadavers. DESIGN: This study is an anatomosurgical description of pelvic and perianal zone and simulation of the different types of supralevator abscesses, their correct drainage routes, and secondary complex fis…

Prognostic Impact of pT Stage and Peritoneal Invasion in Locally Advanced Colon Cancer

2019

BACKGROUND: TNM stage has been identified as an independent variable for local recurrence and survival after colon cancer resection. It is still unclear whether peritoneal invasion (pT4a) is a risk factor for adverse oncologic outcome or whether these patients have better results compared with contiguous organs infiltration (pT4b), independent from nodal status (pN). OBJECTIVE: The purpose of this study was to analyze whether peritoneal invasion is an independent risk factor for worse oncologic outcome after curative colon cancer resection. DESIGN: This was a retrospective analysis with multivariate regression of a prospective database, according to Strengthening the Reporting of Observatio…
